GEORGE KILTZ, OF MARENGO, ILLINOIS.-

CARBURETER FOR GAS-ENGINES.

SPECIFICATION forming part of Letters Patent No. 657,740. dated. September 1 1, 1900.

Application filed April 25, 1900- Serial No. 14.366. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE KILTZ, a citizen of the United States, residing at Maren go, in the county of McHenry and State of Illinois,have invented certain newand useful Improvements in Gasolene-Engines, of which the following is a specification.

The object of this invention is to construct a nozzle for gasolene-engines from which the gasolene is drawn by two currents of air and finely vaporized and in this condition carried into the cylinder of the engine, where it is exploded and consumed.

In the accompanying drawings, Figure 1 is a vertical section of a portion of an air-supply pipe, showing the location of my improved nozzle. Fig. 2 is an isometrical representation of my improved nozzle. Fig. 3 is a vertical section of the same.

A pipe 1 is intended to have a connection with the cylinder of a gasolene-engine, and

p to its lower end is connected an air-pipe 2,

having a controlling-valve 3. An oil-supply pipe 4 is located centrally within the pipe 1, its upper end supportinga nozzle. This pipe has a check-valve 5. The nozzle consists of the lower conical portion 6, having a screwthreaded connection with the oil-supply pipe 4. This lower conical portion has a dishshaped end 7 and an oblique opening-8 extending through the conical portion and opening through the dish-shaped end. A series of small openings 9 are formed in the upper end of the lower conical portion. An upper conical portion 10 has a connection with the dishshaped end 7 of the lower conical portion by three projections 11, leaving open spaces 12 between the projections. With this nozzle located within the pipe 1 and the oil held nearly to the openings 9, when the piston of the engine is moved down it will draw in a charge of air, a portion of which must pass around and along the outside of the nozzle, while another portion will pass through the oblique openingSand out through the openings 12, between the upper and lower conical portions, and thence into the cylinder of the engine. The air in passing around and through the nozzle will draw a charge of oil out through the openings 9, which will mix with the air and become thoroughly vaporized, forming a Very fine spray and forming a proper mixture of air and oil which will readily explode.

I claim as my invention- 1. In a gas-engine, an air-supply pipe, an oil-supply pipe located within the air-pipe and supporting a nozzle at its upper end, the nozzle being in conical form having an upper portion in reverse conical form, a top plate between the conical portions an air passage-way extending obliquely through the nozzle-opening through the top plate, a series of openings through the upper portion above the top plate and a series of openings below the top plate.

2. In a gas-engine, a nozzle in conical form having an upper portion in reverse conical form, a top plate between the conical portions an air passage way extending obliquely through the nozzle-opening through the top plate, a series of openings through the upper portion above the top plate and a series of openings below the top plate.
